摘要： The invention relates to a method and apparatus for estimating a position of a vehicle, in particular an autonomously driven vehicle, by means of an apparatus for ascertaining a position of a vehicle. The invention proposes ascertaining a first absolute position by means of a conventional GNSS receiver. This should be compared with a second absolute position, which is ascertained in a protected safety unit or a protected ASIL-compatible chip, however, and is therefore always plausible.

摘要： The invention relates to a 1st system (3) for receiving and processing satellite signals from satellites of global navigation systems, particularly for a vehicle (F), with a signal path (P1, P2) having: – a signal conditioning unit (4, 5, 104, 105) for conditioning received satellite signals, an analysis unit (6, 106) for analysing the conditioned satellite signals, and – a position finding unit (7, 107) for ascertaining measured values (M1, M2), comprising an ego position (Pos1, Pos2), ego speed (v1, v2) and/or a satellite time (t1, t2), using the satellite signals (S) provided by the analysis unit (6, 106), characterized in that the system (3) has two separate signal paths (P1, P2) that each process mutually independent satellite signals (S) to produce a position (P). The invention also relates to a corresponding method.
